The 50 fastest-growing UK B2B software companies

UK business software companies ranked by two-year growth in turnover, taken from their latest full-year accounts filed at Companies House. Each company is headquartered in the UK, sells software mainly to businesses or the public sector, is not part of another trading group and had turnover of at least £5m. Each is represented by its chief executive, or its executive chair where it has no chief executive. Growth is measured on group accounts, adjusted where an accounting period is not 12 months.
